Flexible thermoelectric materials based on conducting polymers doped with silicone polymer electrolyte

Abstract

Novel conducting polymers doped with siloxane-based polyanion have been synthesized and their mechanical and thermoelectric properties were investigated. Free-standing properties and flexibility of these polymer films were compared with conducting polymers doped with conventional polyanion composed of carbon-carbon backbone. Thermoelectric properties were found to not be affected by the chemical structures of dopant polyanions.

Keywords:

• flexibility
• free-standing films
